What is JDS4?
The key purpose of Joint Danube Surveys (JDS) is to gather vital data on carefully selected elements of water quality across the entire length of the Danube River and its major tributaries.
The project harmonises water monitoring practices across the Danube countries, following the EU Water Framework Directive (WFD) committing member states to achieving good water quality.
Three JDSs have been previously conducted - in 2001, 2007, and 2013 - and the fourth of its kind, JDS4, took place throughout 2019 at 51 sampling sites in 13 countries across the Danube River Basin.
The outcome of the JDS4 should cover the information gaps deemed necessary for the planned 2021 update of the Danube River Basin Management Plan.
